Mounted on the truck platform is a usual derrick mast 9 comprising upright side members Ill, transverse frame members l I, and cross brace members l2, and the mast is pivoted at IS on a base structure |4 carried by the truck platform to swing downwardly into a lowered transport position on the truck in a manner well known to those skilled in the art. The rod line '8 passes through and is adapted to be rotated during drilling by the rotary table vI, also in a well known manner, and comprises a plu-' rality of rods l5 coupled together at l6 by a conis one-end of a spinnin line or cable 48.

4 may be modified to provide different speed ratios to suit different operating conditions. The block frames have guide openings 42 through which the guide rods pass so that the pulley frame 4| of the lower block 2| serves in effect as a sliding cross head. Carried by a cross member 44 of the mast base structure I4 is abracket 4.5;, on which a guide pulley 4'6 is journaled,-and this pulley is arranged in angular relation with respect to the puneys of the pulley block. Attached to the bottom of the frame 36 of the upper pulley block 30 is an eyebolt 41, and connected to this eyebolt This cable extends downwardly from its point of atventional coupling usually embodying coacting.

threaded parts on the adjacent rod-ends. The

so that considerable effort is necessary to effect loosening thereof. The rotary table is driven through suitable transmission connections from conventional engines l1, l1 carried by the truck. In rotary drills of the character disclosed, a fluted or grooved grief stem or kelly is usually attached to the upper endof the rod line, and the rotary table I carries a usual driving bushing which engages the flutes orgrooves of the grief stem so that the latter may be rotated as it slides through the table. When it is desired to "add an additional rod to the rod line or to withdraw the rod line from the drill hole, the grief stem is detached from the rod line, and slips l8 are fitted in the table for supporting the rod line while it is being withdrawn from the hole. As the rod line is withdrawn, the joints l6 between the rods must be quickly disconnected, and after the joints are broken or loosened by the usual make and break tongs, it is desirable to spin rapidly the rod to be uncoupled in order to save time. Also during coupling of the rods, as the rod line is lowered into the hole, spinning in of the rods is similarly desirable.

Now referring to the improved spinning apparatus l for quickly completely uncoupling or for coupling the rod joints, it will be noted that extending vertically lengthwise of the derrick mast 9, when the latter is in its erect operative position shown, at one side thereof is a guideway for a reciprocable pulley block 2 l of a multiple reeve, speed multiplying, cable andpulley mechanism 22. This guideway, in this instance, comtaohment with'the upper pulley block around the pulley 31 of thel ower pulley block, then extends upwardly .and passes around the pulley 32 of the upper pulley block, and then extends downwardly about the pulley 38 of the lower block. The cable then extends upwardly around the pulley 33 of the upper block, then-downwardly around the pulley 39 of the lo'werbloc'k, and then upwardly-around the'pulley-3'4'of the upper block prises parallel guide rods 23, 23 rigidly attached at 24 at their u per ends to an up er frame mermber 25 preferably secured to a transverse frame member of the derrick'mast and at their lower ends at 25 to lugs 21 secured to a cross frame member 28 located at the mast pivot. Loosely surrounding the lower portions of these guides are stop sleeves 29 which provide bottom stops for the guide pulley block 2| in an obvious manner. The cable and pulley mechanism 22 further includes a relatively stationary top pulley block 30 attached by a bolt 3| t0 the upper frame member 25, and carrying a plurality of, herein, preferably three, rotatable pulleys 32, 33 and 34 suitably journaled in'coaxial relation on a cross shaft 35 carried by the upper block frame 36. The lower guided pulley block is reciprocable longitu dinally along the giude rods 23, 23 and carries'a. plurality of, herein preferably three,'pulleys13'|, 3B and 39 suitably journalled in coaxial relation on a cross shaft 40 carried bya lower block frame 4|. It will be evident that the number of the" pulleys and the arrangement of the pulley blocks and has its drop lin'e extending downwardly from the rear side'of the" top pulley 3 to the'guidepulley on the mast base structure H4. The" cable extends substantially horizontally from the guide pulley 46 to the rod line' 8 wherein its intermediate portion is tightly wrapped around or coiled about,at 49, the rod to be rotated, and the free end of the cable extends outwardly at 50 in such manner as to be grasped and held taut by" the operator during the rod spinning operation.-

The improved spinning apparatus is fluid pres sure operated, and there is a vertical fluid cylinder 5| secured at 52 at its lower end to'the top of the'table bed frame 6 and held at its upper end by 'a U-bolt 53 attached to the cro'ss'frame 44 of the mast base structure I4. Contained in this cylinder is a reciprocable piston 54having its piston rod 55 extending upwardly and outwardly through the top cylinder head'and coupled at 56 to the lower end of a'cable 'connection'5l, the latter in turncoupled at 58 toan eyebolt 59 attached to the bottom of the pulley frame 4| of the lower pulley block 2|; The fluid syste nwith which the cylinder is associated is shown somewhat diagrammatically in Fig. 7, and comprlsesa conventional valve block 60 secured to the top'ofthe table bedframe at the s'id'e'op posite'from thespinning apparatus, and having its supply chamber connected by a conduit 6| to the discharge side of a conventionalpump 52,

herein a liquid pump, carriedby the-truck and having its intake connected to'a suitable liquid tank 63.- A discharge conduit 54 leads fromfthe valve box back to the tank, This valve block con tains a conventional control valve -having a suitable operating handle '65 (Fig; 1). Leading from the valve block areconduits 61 and 88 con nected to the opposite endsof the cylinder 5|, as clearly shown, .so that when' the valve is'properly positioned, the piston 54 may be moved under the influence of liquid under pressure in the cylinder either upwardly or downwardly as desired. The fluid system embodies conventional relief valves which may be adjusted in a known mannerso that a predeterminedpressuremay be applied=to the piston 54, which pressure is main- 7, horizontally fromsaid'guid'e' pulley and adapted to 'becoiled about a drill rod to be spun with its free endheld taut by the operator, and means for efiecting fluid supply to said cylinder to effect downward movement of said piston and said lower-pulley block thereby to draw in the end of the cable coiled about the drill rod to spin the latter. l
